Background

The buildings are generally designed with water supply pipes, water discharge pipes, fire fighting pipes and other pipe systems. However, during construction, the piping is usually not started until the civil construction of the building is completed. Therefore, during the civil engineering process, holes need to be reserved for the pipeline system. At present, the mainstream construction mode is to pre-embed a sleeve in the civil engineering construction process, and demolish the sleeve at the later stage, so as to achieve the purpose of reserving a hole.

The existing sleeve is mainly made of stainless steel, and needs to be processed in a processing shed in the using process and then transported to a construction site for use. Because the casing and the concrete are strongly bonded, a large number of workers are required to chisel the casing with a hammer or other tool during the subsequent casing removal process. Thus wasting a lot of manpower; in addition, in the process of chiseling, the sleeve pipe is often damaged to a certain extent, so that the sleeve pipe cannot be reused, and further material resources are wasted.
